Round the Bend by Nevil Shute
When Tom Cutter hires Constantine Shaklin as an engineer in his air-freight business, he little realises the extraordinary gifts of his new recruit. Shaklin possesses a religious power which inspires everyone he meets to a new faith and hope for humanity. As Cutter’s business grows across Asia, so does Shaklin’s fame, until he is widely regarded as a unifying deity. Though he struggles to believe Shaklin is indeed divine, Cutter too finds solace in his friend’s teachings, and commits to passing on his message.
